Top Metrics Every Startup Founder Should Track

As a founder, you're constantly bombarded with data. But not all metrics are created equal. The ones that matter most are the ones that actually tell you whether your business is healthy and on the right trajectory.

Monthly Recurring Revenue (MRR)

For subscription businesses, MRR is the heartbeat of your company. Track it not just in total, but broken down by new MRR (from new customers), expansion MRR (from upgrades), contraction MRR (from downgrades), and churned MRR (from cancellations). This decomposition tells you exactly where growth is coming from and where it's leaking.

Burn Rate and Runway

Burn rate is how much cash you're spending each month above and beyond your revenue. Runway is how many months of cash you have left at your current burn rate. Every founder should know these numbers cold. A good rule of thumb is to always have at least 12–18 months of runway before you need to raise again.

Customer Acquisition Cost (CAC)

CAC is the total cost of acquiring a new customer, including marketing spend and sales salaries. Divide your total sales and marketing spend in a period by the number of new customers acquired in that period. Watch this number over time — if it's rising, your growth is becoming less efficient.

Lifetime Value (LTV)

LTV is the total revenue you expect to earn from a customer over their lifetime with your company. A healthy SaaS business generally has an LTV:CAC ratio of 3:1 or higher. If you're spending $300 to acquire a customer who only generates $200 in lifetime value, you have a serious problem.

Gross Margin

Gross margin is revenue minus cost of goods sold, expressed as a percentage. Software businesses typically target 70–80%+ gross margins. If yours is lower, understand why — it may indicate pricing pressure or inefficient delivery.
